CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This is an unauthenticated SQL Injection vulnerability in the SendPress Newsletters WordPress plugin versions 1.26.1.20 and below. It allows attackers to execute malicious SQL queries without authentication, potentially accessing, modifying, or deleting the entire WordPress database including sensitive user data.

Detection Guidance

Detecting this SQL injection vulnerability requires monitoring for unusual database queries or unauthorized access attempts. Check web server logs for suspicious input patterns like single quotes or SQL keywords (e.g., UNION, SELECT) in POST/GET requests. Use tools like SQLMap to test for injection points in the SendPress plugin endpoints. Monitor database logs for unexpected queries from the WordPress application user.

Impact Analysis

An attacker could exploit this to steal, alter, or delete sensitive data such as user credentials, personal information, or content. They might also gain control over the WordPress site or use it for further attacks. The high CVSS score of 9.3 indicates significant risk of data breaches and system compromise.
